COIN-CONTROLLED TURNSTILE-LOCK- ful Improvements in Coin-Controlled Turnstile-Locks, of which the following is a specification.

This invention is an improved coin controlled lock for use in connection with a turnstile at the entrance to a lace of amusement and to prevent the turning of the turnstile by a person in entering, unless such person has first deposited a coin or check and embodyin means controlled by the coin or check to re ease the turnstile and permit the turning thereof sufliciently to admit such person, when the required check or coin has been deposited, so that the device in connection with the turnstile serves to automatically control theadmission of persons to the place of amusement/and to automatically collect the coins or checks representing the price of admission.

The object of the invention 1s to provide an improved device of this character which is simple in construction, is not likely to get out of order, and which operates. efiiciently for the purpose stated.

The invention consists in the'construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is a perspective view of a coin controlled turnstile lock constructed and arranged in accordance with my invention and showing the'same in use on a turnstile.

Fig. 2 is a plan of the-same, showing the lock casing in horizontal section.

Fig. 3 is a vertical sectional view of the same.

Fig. 4 is a detailed perspective view of the trigger or detent.

- Fig. 5 is a similar view of the locking bar.

For the purposes of this specification a turnstile is indicated at 1, the upright shaft of the turnstile being indicated at 2 and the radial arms thereof at 3. My improved coin controlled turnstile lock is arranged directly above the center of the turnstile and is. here shown as having a cylindrical casing 4 the top and bottom of which are respectively indicated at 5, 6. In one side of thebottom of the lock casing is a segmental recess 7. A similarly-shaped locking bar 8 is mounted on a pivot 9 which is arranged radially of the Specification of Letters iate it.

bottom 6 and midway between the ends of the segmental recess 7. Hence the locking bar is arranged to turn in a vertical plane. Said locking bar is provided with a weighted lower end 10 WhlCh is adapted by gravity to drop behind each arm of the turnstile in succession as the turnstile is partially turned by the passage of persons therethrough and to drop in front of the next turnstile arm and lock the turnstile against the further turning and after said locking bar has been released. The locking bar 8 is provided near the end opposite its weighted end with a stop bar 11 which extends inwardly there-- from and also downwardly when the said locking bar is in normal, horizontal position.

A box 12 for collecting the coins or checks required to operate the lock is arranged in the lock casing and secured on the bottom thereof and is provided in its upper side with a slot 13 Which communicates with the lower discharge end of the coin or check duct 14, the upper open end of which is at the top of the lock casing as shown. Said box is provided in one side with a vertical slot 15. A coin or check controlled trip bar is pivotally mounted as at 17 near its outer end, the inner end of said trip bar being arranged in the box 12 and for operation 1n the slot 15 and being so located that a coin or check which drops through the duct will strike the inner end, of the trip bar and thereby depress the inner end of the trip bar and raise the outer end thereof.

A trigger or detent 18 is arranged at rightangles to the trip bar and at theouter end thereof and with one end'above the outer end of the trip bar. A spring 19 of suitable strength is connected to the bottom of the lock case as at 20 and to one end of the trigger or detent as at 21. The opposite end 22 of the trigger or detent is arranged to operate in an opening 23 in the bottom of the lock casing and is provided with a groove 24 which serves to normally receive the stop bar 11 of the lock bar and to normally hold the latter in turnstile locking, horizontal position. Hence the turnstile is normally locked. When a person attempts'to pass the turnstile he must first deposit the check or coin which represents the price of admission. As the check or coin in dropping strikes the inner end of the trip bar the inner end of the trip bar is depressed and its outer end raised, the trip bar thus causing the outer end of the trigger or detent 18, to be raised against the tension of the spring 19. This causes the inner end of the trigger or detent to move downwardly and to disengage the stop bar 11 which hence releases the lock bar and permitsthe turnstile to be turned. As the turnstile makes the required partial revolution to admit the person, the locking bar is partly turned by one radial arm of the turnstile, said radial arm of the turnstile passing under the lower Weighted arm of the locking bar and said locking bar then immediately reassumes its initial locking position, and is held in such position by the reengagement of its trip bar 11 by the detent or trigger 18, as will be understood.

While I have herein shown and described a preferred'form of my invention, I would have it understood that changes may be made in the form, proportion and construction of the several parts without departing from the spirit of my invention and within the scope of the appended claim.

Having thus described my claim In a coin controlled lock of the class described, a pivotally'mounted locking .bar arranged for movement in a vertical plane and wei hted at one end to move said bar to vertica position when released, a stop element for said bar, a pivotally mounted detent arranged to normally engage said stop element; a spring to normally hold said detent in eninvention, I

gaged position, and a coin operated trip bar arranged when actuated by a coin, to move said detent, to disengaging position and thereby release said locking bar.

In testimony whereof I afiix my signature. JOHN A. STUART.
